No need to use BSD libraries. You can generate invalid binary just using the Apple frameworks (OpenGL, CoreServices).
There is a bunch of symbols which a not properly declared (without the availability macros).
But I think this is something very difficult to fix as Apple didn't managed to do it since I filled radars about it (rdar://7270501 for example) in the early days of Snow Leopard.
But I'm not worry. Some declarations (like CGLTexImageIOSurface2D) may have been fixed in Xcode 4.1…
